METALLIC FABRIC.

SPECIFICATION forming part of Letters Patent No. 416,484, dated December 3, 1889.

Application filed April 24, 1889- Serial No. 308,402. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT T. MGMURRAY, of Brooklyn, in the county of Kings, and in the State of New York,have invented certain new and useful Improvements in Metallic Fabrics; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of a section of my fabric. Fig. 2 is a plan view of the same, and Figs. 3 and 4. are respectively sections upon lines w 90 and z z of Fig. 2.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to produce a metallic fabric which shall be strong, durable, easily constructed, and cheap; to which end such invention consists in a fabric composed of twisted metal strips that are combined in the manner and for the purpose substantially as hereinafter specified.

In the carrying of my invention into practice I employ metal rods A and A, which are preferably square and have such transverse dimensions as will adapt them for the special purpose intended, one eighth of aninch square rods being the size most commonly employed. The rods A and A are arranged in two series,which have a right angle to each other, with the rods of each series alternately passing over and under the rods of the other series, as in ordinary woven fabrics, and having such relative arrangement as to leave within the fabric openings a and a of the desired size. At the intersections of the rods A andA each rod has a curve to around the contiguous rod, which curves operate to securely confine the rods in longitudinal posied possesses in a marked degree strength and rigidity, is ornamental, and can be construct ed at a cost but slightly greater than that of a fabric in which plain round or square rods are employed.

Having thus described my invention,what I claim is- 1. As an article of manufacture, a metallic fabric composed of a series of interwoven rods which at their points of intersection have interlocking curves and between such curves are twisted spirally, substantially as and for the purpose specified.

2. As a new article of manufacture, a metallic fabric composed of a series of interwoven rods which'at their points of intersection are rectangular in cross-section and have interlocking relatively-opposite curves, substantially as and for the purpose specified.

3. As a new article of manufacture, ametallic fabric composed of a series of interwoven rods which at their points of intersection are rectangular in cross-section and have interlocking relatively-opposite curves and between such curves are twisted spirally, substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this 23d day of March, A..D. 1889.

ROBERT T. MCMURRAY.
